TVS - Diodes

The Maxim Integrated MX15KP45A Ultra Low Capacitance AEC-Q101 TVS (Transient Voltage Suppressor) Diode provides efficient and reliable circuit protection for 12V to 24V applications. This diode offers the lowest clamping voltage available, with a maximum IEC 62781 peak pulse current of 15kA. It also offers a remarkably low clamping capacitance, making it ideal for thin and light application designs. It is built using a multi-layered construction for low capacitance values and better clamping performance. This device is ideal for protecting I/O and data lines from harmful transient voltages.

MX15KP45A Application Field

MX15KP45A can be used in a variety of applications, including automotive, industrial, consumer, and home applications. It is suitable for protecting high speed interfaces, such as USB 3.1, and for protecting power supplies and delicate circuits. Additionally, it is suitable for protecting equipment from ESD (electrostatic discharge) and EFT (electrical fast transient) events.

MX15KP45A Working Principle

The working principle of the MX15KP45A TVS diode is based on a Zener breakdown mechanism. This component uses an avalanche breakdown diode, constructed in a specific way to create a precise breakdown voltage.Under normal operation, the voltage across the diode is low, and the current flows through the diode without any effect. In the event of a transient voltage, such as an ESD or EFT event, the voltage across the diode exceeds the breakdown voltage, and the diode begins to conduct current, referred to as clamping. This current flow dissipates the energy of the transient voltage.Once the transient voltage is gone, the diode will stop conducting current and the voltage will drop back to normal levels. This process is referred to as the clamping voltage or the reverse standby voltage, and for the MX15KP45A, it is 8.0V.

Conclusion

The MX15KP45A Ultra Low Capacitance AEC-Q101 TVS Diode is ideal for protecting sensitive circuits from ESD and EFT transient voltages. This diode offers efficient and reliable circuit protection for applications needing low clamping capacitance and low clamping voltage. With its multi-layered construction, it is suitable for 12V to 24V applications, making it an excellent choice for protecting I/O and data lines from harmful transients.
